What are Total Dissolved Solids (TDS)?
You may hear our technicians talk about TDS levels. This refers to the total amount of mobile charged ions, including minerals, salts, or metals dissolved in a given volume of water.
Why does it matter in San Antonio?
Our local tap water often has high TDS levels (300-600+ ppm) due to the limestone aquifers. While mostly safe, high TDS causes "hard" tasting water and indicates the presence of minerals like calcium, magnesium, and even traces of arsenic or lead. Reverse Osmosis is the only way to drop TDS levels to near zero.
- ✓ 0 - 50 PPM: Ideal Drinking Water (Bottled Quality)
- ✓ 100 - 300 PPM: Average Tap Water
- ✓ 500+ PPM: High TDS (EPA maximum contaminant level)
How Reverse Osmosis Works
Reverse Osmosis (RO) forces your tap water through a semi-permeable membrane to remove impurities that standard filters leave behind.
- ✓ Stage 1: Sediment Filter – Removes dirt, rust, and silt.
- ✓ Stage 2: Carbon Filter – Removes chlorine, bad tastes, and odors.
- ✓ Stage 3: RO Membrane – The heart of the system. It filters out up to 99% of dissolved solids, including lead, arsenic, and fluoride.
- ✓ Stage 4: Post-Carbon Polish – A final pass ensures the water is crisp and refreshing.
